I can't speak for OP, but microsoft hasn't had the best relationship with open source in the past,[1] and they are a pretty litigious company.[2] however, their strategy seems to have changed significantly in recent years and I seriously doubt they will change how github operates. if anything, github has improved since it was acquired.
MS has traditionally been a software company, and has a LOT of court experience over the last 40 years regarding copyright and lawsuits when it comes to code and IP. I just think they might have a different viewpoint than GH has traditionally had, since GH's business is completely different than traditional MS businesses. The post I was responding to was talking about GH in the past and what they might do based on that. I'm just saying there's a recently new owner who might look at it differently, so past behavior might not be the best indicator for this since it's being run by a different corporation now.
Since they are a different sort of company, with another legal attack surface.
Going after GitHub means that GitHub has to shut down and the opponent sticks with their legal costs.
When attacking Microsoft they have enough cash to pay you out (in case they lose or they accept a payment to make you shut up) and the case might disrupt Microsoft enough to give you an advantage in a different field.
Not saying that Google would sue Microsoft. Would be very bad for their image. But a risk evaluation is different.
